Here's another image I took while walking around central Amsterdam in the early morning hours. I was only here for a week so I made the decision to stay on North American time. That meant I was still wide awake very late which works well for night photography. I could capture the lights reflecting on the still waters of the canals to my heart's content.
A couple of times I left my tripod back at the hotel. To get these long exposures without shaking the camera I would make due by balancing it on a bike seat. All of the little bridges have bikes leaning against the railings. All I had to do was pick one with a relatively wide seat and gingerly set the camera down. I used a wireless trigger so that I didn't need to touch the camera to activate the shutter.
That little system worked quite well and to be honest, it's a technique I've used in many other places as well. I don't always want to bring a tripod especially when shooting street scenes at night. For that I'm grateful for the high ISO performance of Sony cameras, it allows me to do things that were unheard of just a few years ago. For street photography you want to travel light and be able to react quickly.
Yet when I'm out walking around I'll invariably see something like this scene and I wish I had a tripod. Then it becomes a little game of figuring out what I can use to stabilize the camera. I use all manner of things like balancing on a fence railing, stabilizing the lens with the camera strap, even placing the camera on the ground and shooting up.
As a result I'm hard on camera bodies. They get scratched quite a bit. But for me the scratches on my camera body are like notches on a belt. It's funny but a scratched up camera feels to me like a comfortable set of well worn shows; we've seen a lot together.
